SUGAR-CANE-TRANSFERRING DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 520,271, dated May 22,1894. Application filed December 19, 1893. Serial No. 494,073. (Nomodel.)

To all whom it may concern.-

Be it known that I, ALBERTO SANCHEZ, a sub ect of the King of Spain,residing at Gibara, Cuba, have invented a new and Improved Sugar-Oane-Transferring Device, of which the following is a full, clear, andexact descripion.

The object of my invention is to provide a new and 1m provedtransferring device, which 1s comparatively simple and durable inconstructlon, and more especially designed for conveniently and rapidlytransferring sugar cane from cars to an endless carrier belt deliveringthe cane to the mill.

The invention consists of certain parts and detalls, and combinations ofthe same, as will be hereinafter described and then pointed out 1n theclaims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement, with parts broken out,and the platform and car in a normal horizontal position. Fig. 2 is asimilar View of the same with the platform swung upward. Fig. 3 is anenlarged sectional side elevation of the pivoted end of the platformwith part of the car in 0 position. Fig. 4: is a plan view oftheimprovement. Fig. 5 is an enlarged end view of the cylinder and itssupport; and Fig. 6 is an enlarged transverse section of the carsupporting platform and mechanism for actuating the same.

The improved transferring device is mounted on a suitable foundation A,supporting pillow blocks B, in which are journaled the ends of trunnionsO, forming part of a platform D provided with two rails E, on which thecarF carrying the sugar cane is run from the track on the ground. Theforward ends of the track rails are curved upward, as at E, see Fig. 8,to form a stop for the front wheels F of the car F.

On the trunnions 0, near the middle thereof, is arranged one or severalbumpers 0', adapted to engage the forward end of the platform of thecar, so as to hold the latterin place on the platform D whenever saidplatform is raised for dumping the cane conthe platform of the car F, soas to prevent sidewise displacement of thelatter at the time the car israised. The car F is of the usual construction, and is provided with aplatform and posts F to hold the sugar cane in place on the car.

The free end of the platform D is connected with the upper end of theplunger G of a lifting mechanism Gr, preferably of the hydraulic typeand provided with a cylinder G in which operates the said piston G, andwhich cylinder is mounted on trunnions G turning in suitable bearingsarranged in a pitA formed in the foundation A, and in which the saidcylinder operates. The connection between the piston G and the free endof the platform D is efiected bya ball and socket joint G as is plainlyindicated in Figs. 1, 2 and 6.

One of the trunnions G is made hollow and is connected by a pipe H witha pump I, of any approved construction and driven from the engine J,preferably arranged as indicated in Fig. 4, and of any approvedconstruction. The pump I, forces a fluid under pressure into thecylinder G2 so as to raise the piston G, to impart an upward swinging.motion to the platform D, so as to cause the said platform and the car Fsupported on the platform to assume an inclined position, as is plainlyindicated in Fig. 2. When the car F is in this position its load ofsugar cane can readily be discharged or dumped into the upper end of aninclined cylinder K, open at both ends, the lower end discharging uponan endless carrier belt L, adapted to carry the cane to the mill, to befurther treated in the usual manner.

The cylinderKis provided on its inner face with longitudinally extendingribs K, see

Figs. 4 and 5, so that the material discharged 5 into the upper end ofthe cylinder is agitated by the said ribs, to cause the cane to assume alongitudinal position and be finally discharged upon the carrier beltlengthwise, to be in proper position at the time it reaches the crushingrolls of the mill.

The cylinder K is provided with exterior annular bands K resting onfriction rollers N, journaled in a segmental arm N supported on thefoundation A, as is plainly shown in Figs. 2 and 5. The cylinder K isalso provided at or near its middle with the conical band K engaged atopposite sides of the cylinder by conical pulleys O journaled insuitable bearings erected on the foundation A. The base of the conicalband K is toward the upper end of the cylinder K, and the bases of theconical pulleys O are in the opposite direction, so that the cylinder Kis prevented from sliding downward. The said cylinder K is also providedwith an annular band K over which passes a belt or sprocket chain P,also passing over a pulley P driven from the engine J, itrbeingunderstood that a suitable intermediate mechanism is employed to connectthe said engine with the said pulley P. Thus, when the engine is inmotion, a slow rotary motion is given to the cylinder K, to rotate thesame in its bearings on the rollers N, lengthwise motion of the cylinderbeing prevented by the band K and the conical pulleys O.

As previously stated, the car F carrying the load of sugar cane isprovided with posts F at the sides and ends thereof,but in order topermit the load to be dumped into the cylinder K at the time theplatform D and car F are in an inclined position, as shown in Fig. 2,itis necessary to remove the posts F at the front end of the car, topermit the load to slide off the platform of the car into-the cylinderK. In order to do this I provide a gripping device Q, for each end postthe said device being preferably made in the shape of gripping tongs,see Fig. 1, held on the lower end of a cylinder forming part ofahydraulic or other elevator R, to pull the said end posts F out oftheir bearings in the platform of the car F, so that the load can bereadily discharged into the upper end of the cylinder K whenever theplatform D assumes an inclined position.

By reference to Figs. 1 and 2, it will be seen that the rear end of thecar F is locked in place on the rear end of the platform D by a suitablefastening device S, so as to prevent the carF from leaving the platformD during thedtime the latter is swung upward and lowere The operation isas follows: When the platform D is in its lowermost horizontal position,as illustrated in Fig. 1, then the car F loaded with the sugar cane canbe run onto the rails E of the said platform, and then the car is lockedin place by the rearlocking device S, it being understood that the frontend of the car is held on the bumper C and the upwardly curved ends E ofthe track rails E. The tripping and lifting device Q then engages theposts F at the front end of the car F, so as to remove the said postsfrom the car, after which the operator permits a fluid under pressure topass from the pump I,

through the pipe H and hollow trunnion 6; into the cylinder G to actuatethe piston G so that the latter slides upward and imparts a swingingmotion to the platform D, until the latter with the car F, assumes theposition shown inFig. 2. As the front posts F of the car F have beenremoved, the sugar cane on the platform of the said car will readilyslide downward into the open upper end of the cylinder K, which is thenrevolved, and after the load has been discharged, the operatormanipulates the pump I, so as to permit the piston G to slide downwardin the cylinder G2 to again lower the platform D, until the latterassumes its normal horizontal position to permit the empty car F to bere-- moved and a loaded one substituted to be again treated as abovedescribed. The sugar cane discharged into the upper end of the cylinderK is agitated by the longitudinal ribs K, so that the cane will assume alongitudinal position and finally be discharged at the lower end of thecylinder upon the carrier belt L, to be moved forward by the lat ter tothe crushing rollers of the mill. As the hydraulic piston G movesdownward the fluid in the cylinder runs back through the supply pipe tothe T-valve, from which the fluid passes to the usual storage tank forthe pump, to be used over again by the pump as in all the ordinaryhydraulic jacks. It will be seen that by this arrangement the canerequires no handling by forks or other means to remove the cane from thecar onto'the carrier belt to be carried to the crushing rolls of themill.

The entire machine serves to dump the cane from the car F and to assortthe caneso that it passes lengthwise upon the carrier belt L to be inthe proper position for crushing at the crushing mill.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A sugar cane transferring device, comprising apivoted platform on which the car to be unloaded is run, a liftingmechanism connected with the free end of the said platform, to swing thelatter upward to dump the cane off the car held on the said platform, a.revoluble cylinder arranged in an inclined position and having its upperopen end in close proximity to the pivoted end of the said platform, sothat the cane discharged from the said car passes into the saidcylinder, and

close proximity to the pivoted end of the said platform, so that thecane discharged from the said car passes into the said cylinder,longitudinal ribs arranged within the said cylinder to straighten thecane discharged therein, and a carrier belt upon which discharges thelower end of the said cylinder to carry the cane in an assortedcondition to the crushing mills, substantially as shown and described.
